Research Shows Ventilated Auto Seats Improve Fuel Economy, Comfort

06.03.2006
The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) has demonstrated that ventilated automotive seats not only can improve passenger comfort but also a vehicle’s fuel economy. That’s because ventilated seats keep drivers and passengers cooler, so they need less air conditioning to be comfortable.

NREL’s Vehicle Ancillary Loads Reduction team has been working with industry to try to reduce fuel consumption from air conditioning in cars and trucks. The use of ventilated seating is one way to cut air conditioning, and recent research shows that it works.

"If all passenger vehicles had ventilated seats, we estimate that there could be a 7.5 percent reduction in national air-conditioning fuel use. That translates to a savings of 522 million gallons of fuel a year," said John Rugh, project leader for NREL’s Vehicle Ancillary Loads Reduction Project.

W.E.T. Automotive Systems Ltd. provided NREL with ComfortCools® seats for testing. Each seat contains two fans that pull air from the seat surface and out from underneath the seat. General Motors currently offers this ventilated seat as an option for the Cadillac STS.

Using its suite of thermal comfort tools and subjective test data, NREL measured improvement in human thermal sensation for the ventilated seats and the potential for a 7 percent reduction in air-conditioning compressor power.

NREL developed its thermal comfort tools to help the automotive industry design smaller and more efficient climate-control systems in vehicles. The tools consist of a one-of-a-kind thermal comfort manikin called ADAM (ADvanced Automotive Manikin)—which actually breathes and sweats—along with a physiological model and psychological model. Linked together, these tools assess comfort in a transient, nonhomogeneous environment, unlike other commonly used models based on steady-state, uniform environmental data.

NREL is the U.S. Department of Energy’s (DOE) primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for DOE by Midwest Research Institute and Battelle.

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
